<p>当你的触摸板无法正常工作时，或者一点也不工作时，那你可能就需要修改ACPI来修补修补你的触摸板来，使其能够正常工作。<br>
毕竟一台笔记本电脑，用不了触摸板实在是太难受了。（如果你有钱买妙控板，那就另当别论了）</p>
<h1 id="确定设备路径">确定设备路径</h1>
<p>1.进入<strong>Windows系统</strong>，打开<strong>设备管理器</strong>，找到<strong>人体输入学设备</strong>，确认自己是不是I2C触摸板（有可能是I2C USB），如果不是I2C，请跳转到<strong>安装步骤</strong>。<br>

<p>2.然后右键查看属性，在详细信息里找到触摸板的<strong>位置路径</strong><br>

<p>像这里的路径就是：<br>
<code>_SB.PCI0.I2C0.TPD0</code><br>
我们把它记下来吧，之后会用到。</p>
<h1 id="确定acpi-pin">确定ACPI PIn</h1>
<p>到Mac系统下，使用<strong>IORegistryExplorer</strong>查看<strong>ACPI Pin</strong><br>
在右上角搜索自己的触摸板名称，比如根据我们之前照出来的路径，触摸板设备的名称就为<strong>TPD0</strong></p>
<blockquote>
<p>常见的触摸板名称，如，TPD0，TPDX，ETPD，TPAD等<br>
常见的触摸屏名称，如，ETPD，TPLX等</p>
</blockquote>
